understandably i am fast running out of space with two operating systems and apps on one disk! I have been considering upgrading to the momentus Xt 500gb HD - hybrid drive
My question is - has anyone tried this hardrive on a late 2008 macbook pro4,1 with dual operating system via bootcamp and if so are there any known issues - i understand the firmware update for the xt has brought about many fixes. Is it even compatible with this model which i bought 5 days before the launch of the unibody. - this was a conscious decision as i had my heart set on the classic look (not a fan of the non-chamfered black keys!

I'm not sure, I have just heard that there are an unusual number of bad drives for that model. I doubt that it's very common, just more so than others. If you get a good one to begin with, it should last you quite a while.

In all honest, I've heard more horror stories about those drives than good. Also, they've been out a while, and no other manufacturer has bothered releasing a competitor. That should say something (in a bad way).

But the most important point, the 4GB of flash on that drive acts like a cache. It speeds up whatever program/activity you do the more you do it. However, that starts over when you boot into a new partition. So if you're jumping back and forth from OS X to Windows a lot, you're probably not going to see any huge gains. Even at its best, the XT isn't anywhere near as fast as an SSD. 500GB WD Scorpio Black drives can be had for fairly cheap, and they're pretty much one of the fastest mechanical 2.5" drives on the market.
